I hear this faint clicking sound coming from the earpiece whenever I'm on a phone call. I can hear the other person well enough, but the sound is rather obnoxious. It doesn't happen on every call (for a while I thought it was only when I was listening with my left ear, but that didn't turn out to be the case). It's been like this for a while, and I've just ignored it b/c I don't make a ton of phone calls. However, since the warranty is up in about 2 months, I'd like to get this addressed since I'm going to have this phone for another yr. Has anyone else had this issue / have any suggestions?
